Abstract
Frequency of the lines of the Swan spectrum.—Data obtained by Leinen, Komp, Hindrichs and Johnson have been used in a detailed quantum analysis of the Swan bands. The very recent data by Johnson have been employed only in the study of the multiplicity of the lines. Tables of the frequencies of the lines and their combination differences are given for the (0, 0), (0, 1), (1, 0), (1, 1) and (1, 2) bands.
